Indaba Eyisibonelo: Isibonelo Sokusebenza Samavalvu Ase-American Standard Cast Steel Globe Emazingeni Okushisa aphezulu kanye Nezimo Zengcindezi Ephakeme

"Indaba: Isibonelo Sokusetshenziswa Kwe-American Standard Cast Steel Globe Valves Emazingeni Okushisa aphezulu kanye Nezimo Zengcindezi Ephezulu"

Ama-valve eglobhu ensimbi ajwayelekile aseMelika avame ukuhlangana nezimo eziphakeme zokushisa nezimo ezicindezelayo ezinhlelweni zezimboni, ezibeka phambili izidingo eziphakeme zezinto ezibonakalayo, ukwakheka, nokusebenza kwevalvu. Lesi sihloko sizohlola ukusetshenziswa kwamavalvu eglobhu ensimbi ajwayelekile aseMelika endaweni enezinga eliphezulu lokushisa kanye nengcindezi ephezulu ngecala elithile, futhi sihlaziye izici ezibalulekile ekwakhiweni kwawo nasekusetshenzisweni kwawo.

Ingemuva lendaba:

Kuyunithi yokucwenga yebhizinisi le-petrochemical, ivalvu yeglobu yensimbi evamile yaseMelika iyadingeka ukuze kulawulwe ukuhamba kwemidiya ye-hydrocarbon ngaphansi kwezinga lokushisa eliphezulu nokucindezela. Izinga lokushisa ngaphansi kwalesi simo sokusebenza cishe li-400 ° C futhi ingcindezi ifinyelela ku-150MPa. Ngenxa yokugqwala okuphezulu nokuvutha kwe-medium, izidingo ezikhethekile zibekwe ekukhethweni kwama-valve.

1. Amaphuzu wokuklama

1. Ukukhetha izinto ezibonakalayo: Uma kucatshangelwa izici zokushisa okuphezulu, ukucindezela okuphezulu, nemidiya edlayo, ivalvu yeglobu yensimbi evamile yaseMelika eyenziwe ngezinto zensimbi ye-alloy yakhethwa. Le nto ingagcina izakhiwo ezinhle zemishini emazingeni okushisa aphezulu futhi inokumelana okuphezulu nemidiya egqwalayo.
2. Umklamo wesakhiwo: Ukuze umelane nokucindezela okukhulu, i-valve ithatha igobolondo eliqinisiwe kanye nomklamo we-disc ukuze kuqinisekiswe ubuqotho besakhiwo se-valve ngaphansi kwengcindezi ephezulu. Ngesikhathi esifanayo, isakhiwo sokuvala uphawu kabili siyamukelwa ukuze kuzuzwe umgomo wokuvuza kwe-zero.
3. Ukucatshangelwa kokukhuphuka kwezinga lokushisa: Ezindaweni ezinezinga lokushisa eliphezulu, ukusebenza kwezinto zama-valve nama-seal kungase kuthinteke. Ngakho-ke, enkambweni yokuklama, kuyadingeka ukucabangela i-coefficient yokwandisa ukushisa kwezinto kanye nokusebenza okuqinile kophawu emazingeni okushisa aphezulu.
4. Ukuhlola kanye nesitifiketi: Ukuqinisekisa ukuthi i-valve ingasebenza ngokuphepha ngaphansi kwezimo zangempela zokusebenza, ukuhlolwa kwengcindezi eqinile nokuhlolwa kokusebenza kwempahla kuye kwenziwa, futhi kutholwe izitifiketi ezifanele zokuphepha.

2. Umphumela wohlelo lokusebenza

1. Ukuphepha: Ngemva kokufakwa, i-valve yeglobu yensimbi evamile yaseMelika iphumelele ngempumelelo ukuhlolwa komkhiqizi kanye nokuhlolwa kwendawo, okuqinisekisa ukusebenza okuphephile ngaphansi kwezinga lokushisa eliphezulu nezimo zengcindezi ephezulu.
2. Ukuthembeka: I-valve ibonise ukuzinza okuhle ngesikhathi sokusebenza, ngaphandle kokuvuza noma amanye amaphutha, iqinisekisa ukuqhubeka kokugeleza kwenqubo.
3. Ukumelana nokugqwala: Ngenxa yokukhethwa kwezinto ezifanele, i-valve ibonisa ukumelana nokugqwala okuhle lapho ibhekene nemidiya egqwalayo, inweba impilo yesevisi ye-valve.

Isifinyezo:

Ukusetshenziswa kwamavalvu eglobhu ensimbi ajwayelekile aseMelika endaweni enezinga lokushisa eliphezulu kanye nengcindezi ephezulu kudinga ukucatshangelwa okuphelele kwezinto eziningi njengokukhethwa kwempahla, ukwakheka kwesakhiwo, imiphumela yokwenyuka kwezinga lokushisa, kanye nesitifiketi sokuhlola. Ngocwaningo lwaleli cala, singabona ukuthi ngokuklama okunembayo nokukhethwa kwezinto ezibonakalayo, ama-valve eglobhu ensimbi ajwayelekile aseMelika anganikeza izixazululo eziphephile, ezinokwethenjelwa, nezisebenza kahle ngaphansi kwezimo zokusebenza ezinzima. Lokhu kunenani elibalulekile lereferensi yezinhlelo zokusebenza zezimboni ezifana nezimo ezishisa kakhulu nezinomfutho ophezulu wokusebenza.
